We are now seeing that global communities of users are able to collaborate effectively to create detailed, useful content on the Web for the benefit of others. Folksonomies and applications such as Flickr, YouTube and del.icio.us that are based on simple social tagging suggest that the power of these Web communities could be harnessed to create, update and maintain content annotations for multimedia resources. However, a dearth of empirical research has been carried out to understand how users work with these types of tools. In this chapter, we report the results of an experiment that collected data from users using both folksonomic (Flickr, YouTube and del.icio.us) and MPEG-7 tools (COSMOSIS) to annotate and retrieve media. We contribute a conceptual model for each type of tool that illustrates the tag usage. These conceptual models are then exploited in the development of an MPEG-7 profile for multimedia annotation communities. |
